A positive QFT-Only result indicates TB infection but does not differentiate between latent tuberculosis infection (LTBI) and active, communicable disease. Advantages Over Historical Methods.
Understanding Quantiferon Criteria Negative Result High Risk
Understanding these thresholds is fundamental for clinicians to move beyond simple laboratory output and apply the data accurately within a patient’s clinical context, distinguishing between latent infection and active disease with confidence. Factors such as symptoms, chest radiograph findings, and epidemiological risk are essential to determine the appropriate clinical management, whether that is preventive therapy or a full course of anti-tuberculosis treatment.
7 antigen, which is less prevalent in non-tuberculous mycobacteria. Therefore, the strictest adherence to the quantiferon criteria must be coupled with a thorough clinical assessment.

Specific Antigen Responses Modern QFT-Plus assays evaluate responses to multiple antigens, and the criteria account for each component. Quantiferon criteria serve as the essential framework for interpreting the QuantiFERON-TB Gold Plus (QFT-Plus) test, a critical tool in the diagnosis of tuberculosis infection.
